Pick the WRONG design guideline for a reactor in which the reactions, A → R (desired) and A → S (undesired) are to take place. The ratio of the reaction rates is rR/rS = (k₁/k₂).Csub>Aa-b Avoid recycle, when a > b Use high pressure and eliminate inerts, when a > b Use batch reactor or plug flow reactor, when a > b Use CSTR with a high conversion, when a > b TRUE ANSWER : ? YOUR ANSWER : ?
The gas phase reaction 2A ⇋ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is 43833 43864 43898 43959 TRUE ANSWER : ? YOUR ANSWER : ?
